WORK 'CLAMP Fild Jan. 25, 1936 2 Sheets-Sheet 2 Inuenlor Patented Sept. 8, 1 936 UNITED STATES :P'ATENT OFFICE 2,053,459 5 wonx oLAMr I v Frank B. Brown, Riverside, R. I. a I Applicatin'January'23, 1936, Serial No. 60,540 3 Claims. (01. 29--sr) The present invention relates to new and useful improvements in 'miter boxes, particularly for metal work, although it will be understood that a device constructed in accordance with the present invention may be used for any other material and for any other purposes for which it may be found adapted and desirable.

One of the important objects of the invention is to provide, in a manner as hereinafter set forth, a device of the aforementioned character embodying novel means through the medium of which pieces of work of various shapes maybe rig-idly clamped in position to be operated on, the clamping means further permitting one or more pieces to be secured'at a time.

Another very important object of the invention is to-provide novel means for detachably and adjustably securing the device to a base.

Other objects of the invention are to provide a miter box of the character described which will be comparatively simple in construction, strong, durable, highly efficient and reliable in use, compact, light in weight and which may be manufactured at low cost. p

All of the foregoing and still further objects and advantages of the invention will become apparent from a study of the following specification, taken in connection with the accompanying drawingswhereinlike characters of reference designate corresponding parts throughout the several views, and wherein:-

Figure 1 is a view in side elevation of a miter box constructed in accordance with the present invention, a portion of the socket and post being broken away in section.

Figure 2 is a view in front elevation of the miter, box, and clamp.

Figure 3 is a view in vertical transverse section through the rear end portion of the box, taken substantially on the line 33 of Figure 1, showing a piece of work in position.

Figure 4 is a view in vertical transverse section through the box, showing a substantially T-shaped bed mounted therein to accommodate flat work.

Figure 5 is a view in vertical transverse section through the box, showing a plurality of pieces of round work clamped therein.

Figure 6 is a detail view in perspective of the bed which is used when a plurality of pieces of round work are to be clamped in the box, as-

shown in Figure 5.

Figure 7 is a view in side elevation of a portion of the invention, showing the box swung to a vertical position.

in Figure 8.

Referring now to the drawings in detail, it "will be seen that the'embodiment of the inven- "tion'whichhasbeen illustrated comprises a base saw (notshown). gidly secured on Figure-8 'is a view in front elevation of the invention, showing'the device being used for soldering. r I

Figure 9 is a detail view in perspective of the 'detachable table which is attached to the miter when the -device is used for soldering, as shown 7 l which is rigidly and permanently secured to a "bench or other suitable support 2 by bolts or the like '3; The base I includes a socket 4 for the reception of an adjustable and removable post 5 j whichis secured in position by a set screw 6.

" In-its upper end portion the post 5 has formed therein avertical slot or groove 1 which is travas at I I, for supporting the miter I 0 in a vertical position, as illustrated to advantage in Figure 1 o'fthe drawing. The miter I0 includes oppositely inclined arms I2 terminating in vertical free end portions I3, said arms I2 and portions 'I3 having slots I4 therein for the reception of a at right-angles therefrom is a substantially V- shaped box I5 for the reception of the Work I6, as best seen in Figures 3 and 5 of the drawings. In its rear end portion, the box I5 has formed in its bottom an opening I? for the reception of a center punch or drill. The work is'removably secured in the box 55 through the medium of a clamp which is designated generally by reference numeral I8. The clamp I8 comprises a metal bar bent to form a horizontal intermediate portion I9, oppositely inclined portions 20, and inturned end portions 2| constituting hooks engageable under the walls of the box I5. The portions 19 and 20 of the clamp I8 have threaded openings 22 therein which accommodate Winged clamping screws 23. When a single piece of work is to be secured, as seen in Figure 3, but a single clamping screw 23 may be necessary, this being the one which is mounted in the portion I9. However, when a plurality of pieces of work are to be secured in position a number of clamping screws may be used, as shown in Figure 5 of the drawings. When a plurality of round pieces of work are to be secured in the box I5, a metallic plate 24 of angular cross-section is mounted on the lowermost piece of work in the the miter I 0 and projecting bottom of the box IE for the other pieces to rest on. When it is desired to secure flat work in the box l5, a substantially T-shaped bed 25 (see Figure 4) is mounted in said box. The bed 25, it will be observed, may be made from two lengths of angle iron rigidly secured together.

The construction and arrangement is such that the miter I0, with the box I5 thereon, may be swung to the position shown in Figures 7 and 8 of the drawings, in which position said miter l0 rests on the bottom of the groove 1 in the post 5. When in this position, the device may be used for soldering by securing an electric soldering iron 26 in the box 15. Then, a table 21 is mounted on the now horizontal miter III. The table 21 includes a substantially V-shaped extension 28 which projects into the box IE below the soldering position, as shown in Figure 1 of the drawings,

one or more pieces of work may be expeditiously secured in position in the box l5 through the medium of the clamp 18, said pieces, of course, traversing the slots M in the miter l0 for engagement by the hack saw, as will be obvious. As hereinbefore stated, the mounting of the miter Ill permits the device to be readily adjusted. Further, the miter In with the box 15 may be conveniently removed when desired for any purpose.

It is believed that the many advantages of a .miter box constructed in accordance with the present invention will be readily understood, and

although a preferred embodiment of the device movably and adjustably secured in said socket, means for securing the post in adjusted position, said post having a groove in its upper end portion, said groove being closed at one end, a substantially Y-shaped clamping member mounted on the post and including a shank journaled in the groove, said shank being engageable with the end wall of the groove for supporting the clamping member in a vertical position and being further engageable with the bottom of said groove for supporting said clamping member in a horizontal position, and a substantially V-shaped box rigidly mounted on the clamping member, said clamping member having slots therein for the reception of a saw.

2. A device of the class described comprising a post, a-member mounted for swinging movement in a vertical plane on said post, a substantially V-shaped box mounted on said member, a table removably mounted on the member and including a substantially V-shaped end portion engageable in the box, and means for removably securing a soldering iron in the box. 7 V

3. A device of the class described comprising a base including an upstanding socket, a post mounted in said socket, said post having a groove in its upper end portion, said groove being closed at one end, a member mounted for swinging movement in a vertical plane on the post, said member including a pair of oppositely inclined arms and a shank journaled in the groove, said shank being engageable with the end wall of the groove for supporting the member in a vertical position and being further engageablewith'the bottom of the groove for supporting said member in a horizontal position, parallel extensions on the free ends of the arms, a substantially V-shaped box rigidly secured on the arms of the member, a table, for supporting a quantity of solder, removably mounted on the member, said table including a substantially V-shaped extension projecting into the box and further including depending sides, inwardly and upwardly turned flanges on the lower ends of the sides engageable with the parallel end portions of the arms for removably mounting the table in position on the member, and a clamp on the box for detachably securing a soldering iron in said box.
